![]() They are intelligent because you can modify them in different ways. ![]() Or to be more precise, they are like intelligent 3D polylines. In case you are not familiar with these, feature lines are just like ‘clever’ lines. To create a grading, you will need to start with a feature line. If you are using the UK and Ireland (UKIE) Country Kit from Autodesk, you will find many Civil 3D grading settings ready for you to use. This surface will be your base or datum for volume comparisons. Drainage and flood zones are additional key constraints which are sometimes overlooked, with potentially catastrophic consequences.īefore creating a Civil 3D grading you will need to set up the existing ground – often called ‘EG’ – as a surface. Also, the existing ground levels and constraints will affect the geometry of your site, both in plan and profile. The available space and surrounding stakeholders will determine how much land you can use. ![]() After defining the needs, it is important to look at the existing ground conditions and constraints. It is not the same designing a small parking lot for a family home than a large site for commercial development. Firstly, you will need to assess the needs and requirements of your site. There are several important factors to consider when designing gradings and sites. How to get started with Civil 3D gradings Although it is still possible to use Civil 3D corridors to design and 3D model those features, it is more efficient to use Civil 3D gradings. However, they are not so easy to use when it comes to designing features like sites, parking lots or building pads. Civil 3D corridors, for example, are great to design linear infrastructures, such as highways and railways. This article will explore what they are and how to use them.Īs we mentioned in a previous article, Civil 3D is a powerful software to deliver BIM services. ![]() From surfaces to cut and fill calculations, Civil 3D gradings can help you save a lot of time and effort. Civil 3D gradings are one of the most useful tools for site design in the engineering industry. ![]()
